Rahul was a sharp and intelligent boy. One day, his father got back from his office and called him in a harsh tone. Rahul got frightened and came immediately.
He thought, "Dad just arrived from his office. Why is he calling me so harshly? Is he angry with me?"
Father said in a rough tone, 'Coincidentally, I met your teacher and she told me that everyday you reach school late. Why?"
Rahul thought for a while and said, 'I'm not responsible for anything. They ring the school bell before I reach the school."
Father praised Rahul for such a witty answer, but asked him to reach the school on time.
